Embodiment Construction

[0024] Such as figure 1 Shown, a kind of privacy protection system based on broadcasting and attribute encryption technology is made up of location sharing server group, roadside unit RSU (Road-Side Units) and vehicle-mounted unit OBU (On board Unit); Described location sharing server group , RSU and OBU are interconnected through wireless network.

[0025] Such as figure 2 As shown, a privacy protection system based on broadcast and attribute encryption technology realizes the privacy protection method as follows:

[0026] Step 1: The on-board unit OBU uses an attribute-based encryption algorithm to encrypt the on-board unit OBU identification set, and periodically sends the location information, time, and encrypted on-board unit OBU identification set to the roadside unit RSU;

[0027] Step 2: The roadside unit RSU uses the private key to decrypt the identification set of the on-board unit OBU, encrypts the collected information with the identification set of the on-board...

Abstract

A privacy protection system based on the broadcast and attribute encryption technology comprises a location sharing server group, road-side units (RSU) and an on board unit (OBU) which are all interconnected through wireless networks. The privacy protection system based on the broadcast and attribute encryption technology has the advantages that by utilizing two mechanisms of broadcast encryption location information and anonymization OBU identification, the location sharing server group cannot obtain accurate user information; by utilizing the mechanism based on the attribute encryption, the identification of a user is ensured to be only deciphered by the real RSU; the mechanism based on the attribute encryption is utilized during the location sharing of the user, and persons reading the location information can be effectively and flexibly limited through the mechanism.

Description

technical field [0001] The invention relates to the field of privacy protection of the Internet of Vehicles, in particular to a vehicle location privacy protection system for the Internet of Vehicles based on broadcast and attribute encryption technology. Background technique [0002] With the large-scale and high-frequency use of vehicles in modern society, through the establishment of vehicular ad hoc networks (VANETs), also known as the Internet of Vehicles, the Internet of Vehicles constitutes the basic environment of the "smart car" network. The driving experience can be effectively improved through the Internet of Vehicles, and the driver can effectively use the location sharing service to deeply understand the real-time driving environment and accurately locate the location of the surrounding friends. [0003] However, the Internet of Vehicles has the problem that privacy is easily leaked. Since the third party that provides location sharing services can collect the ...
